For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.

In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for my understanding. I need to have a visual picture in my mind. I'm constantly translating from the math to some intuitive mind's-eye picture.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

My grandmother was energetic and fearless - a talented poet and songwriter. She was also interested in chemistry and history and medicine, taking care of the people in her hacienda in Mexico, delivering babies. She could have become anything, but this was the 1930s, and she was forced into an arranged marriage.

People commonly travel the world over to see rivers and mountains, new stars, garish birds, freak fish, grotesque breeds of human; they fall into an animal stupor that gapes at existence and they think they have seen something.

The greatest discovery of my generation is that a human being can alter his life by altering his attitudes.

Some people become passionate readers and fans of science fiction during childhood or adolescence. I picked up on SF somewhat later than that; my escape reading of choice during my youth was historical novels, and one of my favorite writers was Mary Renault.
